PITTSBURGH – Starting tomorrow, autonomous robots from 11 teams will descend into an underground mine outside of the city for the first stage of DARPA’s multi-year Subterranean Challenge. Teams will face a simulated mine disaster, with a mission to create 3D maps of the underground mine, and identify several prepositioned objects and “human survivors.” With a combination of robots and drones to navigate the environment, teams will have 60 minutes each to complete the mapping and search mission.
